Paper Abstract

We propose to use the rare-earth-doped silica as the IR-to-visible converter. We describe its principle of operation employing the up-conversion upon pumping with the near IR radiation. We developed a time-dependent 3-D heat transfer model for fiber geometry with finite element method. We present results of the study to determine spatial and temporal resolution of this transducer for the constant and impulse irradiation profile. We conclude that better temporal and spatial resolution is achieved when the fiber is in contact with a cold reservoir. The cold sink also assists in the rapid response of the device, as the latent image is quickly erased.
